They cancelled gigs in Munich, Germany and Vienna in Austria this week (beg21Nov11), and are yet to confirm whether Friday's (25Nov11) planned performance in Amsterdam, Holland will go ahead. In a statement on their website, the rockers write, "Thanks for hanging in there with us and we hope to see you all soon!"
